TO ALL WHOM IT MAY GONCERN:

Be it lknown .that I, RICHARD EATON, of Montrealyanada, have inventedfav new `sind improved Freight Railroad Car;` and I do hereby declare that the following is `a full,clear, and exact description thereof, which will enable'others skilled in the artto make and use the sanne, reference being had to lthe accompanying drawings, forming part 'of this specication, in which-f.

Figure 1 is a side elevation of a freight car, partly in section, taken inthe line :1i-az, fig. 2.

Figure 2 is aninverted plan, with interior parts exposed. i

Figure 3 is an enlarged vertical section of a detached part.'I

Figure 4 is a horizontal section, in part, o'f a car.' i

Figure 5 is an enlarged plan of the crown plate detached. Similar letters of referenceindicate like parts.

This improvement relates -to the construction of railroad freight cars, and is designed for increasing largely. the capacity of a car for carrying freight. This object is accomplished by applying to a car two six-Wheeled trucks with cogged friction-rollers,.on-which the body of the car rests, so constructed and arranged that the weight of thecar and its load is equally divided and distributed upon thewheels and axles,2 thus allowing -a heavier load to be put on the car without increasing the strain on any one of them. In constructing ,theA car I reducev the dead'lweightfvery materially by substituting wrought for `cast iron whenever Ait is possible, and particularly with the crown and centre plates, the buffer-boxes .-or draw-heads, and the axle-box guards or housings. Also, by making the roof of the car of sheet iron or steel, and setting strong and lightlyeconstructcd uprights at the' sides and ends of the car at proper distances from'each other,vto receive an upright'flour barrel between them. By the diminution of dead Weight thus effected in the construction of the freight car and the use of,si x-wheeled trucks arranged as hereinafter' described,'I am enabled to double nearly -or` quite the freight-carrying capacity of a car, or, in other, words, carry two tons of freight to'ono of dead weight, instead of one to one,.according to the general rule with freight cars of ordinary construction.4 The practical advantage of this improved mode of constructing freight cars is that a train will 'be able to carry from thirty per cent.` to fty per lcent. more paying freight, with the same hauling power of a locomotive, and thus largely increase the business andrevenuc of a railroad with the same amount of rolling stock.

A. Arepresents the supporting frame of the body of the-car built in the ordinary way; B B are uprights on 'the sides and ends, to which the sheathing C Cis fastened, which may be made of wood or sheet iron, The roof D DI make of sheet iron, either ilator corrugated, with ventilators in the top of the .car when fiat, or, when corrugated,forrncd by the corrugations of the overbanging' sides or eaves, to prevent overheating of the perishable freight in warm weather.l The openings for ventilation should bc protected bywiro'gauze placed over them. E isthe crown plate, andE the centre plate, madeof wrought iron, the former shown on an enlarged scale in 5, made as light as possible by cutting ontholcs, a a a a, to rid it of surplus metal. vThe bu'erboxes 'cr drdW-heads F F are also made of wrought iron instead of cast iron, commonly used for the purpose, and open at the sides for the double purpose of admitting springs and lessening .theweight of surplus inetal. They are attachedto the frame longitudinally by langes on .their sides and to the head-stock by angle-iron brackets. GG are the six-wheeled trucks, .withtheir wheels, I I I, protected bysheet-iron housings or guards, H H, which are stiifened by flaty or angle-iron knees or brackets, b b b, fig. 1, with their lower ends fastened to supporting bars, c c c, placed directly under the axle-boxes d d du `The outside truck frames, G G,are connected by cross-beanis`cr holsters, K K,-which'are also connected inthe middle .bythe saddle L, on the upper side -of which is lfastened the lower 'centre plateE, the whole being sustained and kept .in position by the central doubleheaded bolt e, as shown by iig'. 3; `Between thev upper edg'e of the sides of the trucks and the bottom of the car 'over the middle wheel, are placed frictiou-cogged rollers, f f, figs. 1 and 2, which play loosely b'etween iron or steel bearing-plates above and below, and allcw'n triiiing oscillatingA or vibratory movement pi' the trucks,while they are held in place bythe cogs or projections 'formed by little bars or studs on both sides of the rollers,

which set into recesses ,inthe containing frictionor bearing plates above and below the rollers. p The cogs pre- `-lgent the rollers from slipping or from being moved or .jammed out of place. The weight of the body of the :ar

rests upon the friction-rollers, and they have suilcient side play to permit of theeasy movement and adaptation of the trucks to any curves of the ralroaditrack. The trucks a're'prevented from slueingaround too far by the overlappingof the cross-beams or holsters K'K 4upon the outsides of the trensoms or holsters M M placed on the under side ofthe car, to which .the crown ,plete E is fastened, (figs.A 1 and 2,) while', however, suiicient space is left between the holsters to suit the curves of the road. Around the interior of the car, securely fastened to the 'uprghts B B, ere placed two or more light horizontal iron bands or hoop-iron straps, g g, at suchrl'stances above the floor of the car as to reach the middle of the flou. or other barrels, 71 ler'arranged on end in tiers, as shown in figs. 1 and 4. Between the tiers oi' barrels thus loaded in a. car 'I nd great advantage in p'lecing a. light and-strong board or frame, to keep the load steady in place and protect the chinos pf the'bariels..

Having described my improvement and its advantages, what I claim as neme-.nd desire to secure by Letters Patent, is

1. I claim the truck for freight cars with six wheels alnd wroght-iron housings, H, constructed-end arranged substntially 'as and for the purpose described.

2. I claim the cogged friction-rollers f f, placed between beaming'plates on the car bed and truck frame, respectively, and operating substantially as described.
